NSTALLATION OF THE RIGHT SIDE ASSEMBLY
Follow steps 1-5, reversing all orientations, for assembly and installation of the driver’s side assembly. Both air helper
springs will install just to the rear of the axle.

NSTALL THE AIR LINE AND INFLATION VALVE
Uncoil the air tubing and cut it into two equal lengths. DO NOT FOLD OR KINK THE TUBING. Try to make the cut as square as
possible. Insert one end of the tubing into the elbow fitting installed in the top of the air helper spring. Push the tubing into the fitting as
far as possible.
Select a location on the vehicle for the air inflation valves. This can be on the bumper or the body of the vehicle, as long as it is protected
so the valves will not be damaged (see Figure “D”). Drill a 5/16" hole and install the air inflation valve using two 5/16" flat washers
per valve as supports (see Figure “E”). Route the tubing from the air helper spring to the inflation valve, avoiding direct heat from
the engine, exhaust pipe, and away from sharp edges. The air line tubing should not be bent or curved sharply as it may buckle with age.
Secure the tubing in place with the nylon ties provided. Push the end of the air line tubing into the inflation valve as illustrated (see Figure
“E”).

HECK THE AIR SYSTEM
Once the inflation valves are installed, inflate the air helper springs to 50 psi and check the fittings for air leaks
with an applied solution of soap and water. If a leak is detected, deflate the air spring by depressing the valve core.
The tubing can easily be removed from the fittings by pushing the collar on the fitting towards the body of the fitting
while pulling out the tube. Next, check the tubing connection to ensure that the air tubing is cut as square as possible
and that it is pushed completely into the fitting.
If a leak is detected where the air fitting screws into the air spring, gently tighten the air fitting into the spring
until the leak stops. Also, check the core of the inflation valve. This valve core can be tightened using the cap.
Re-inflate the air spring and check for leaks again if needed.
This now completes the installation. Install the wheels and torque the lug nuts to the manufactures specifications.
Raise the vehicle by the rear axle and remove the jack stands and lower the vehicle back onto the ground. Re-
attach the negative battery cable and remove the wheel chocks from the front wheels. Before proceeding, check
once again to be sure you have proper clearance around the air springs. With a load on your vehicle and the air
helper springs inflated, you must have at least 1/2" clearance around the air springs. As a general rule, the Air
Helper Springs will support approximately 30 lbs. of load for each psi of inflation pressure (per pair). For example,
50 psi of inflation pressure will support a load of approximately 1500 lbs. per pair of air helper springs. FOR BEST RIDE
use only enough air pressure in the air helper springs to level the vehicle when viewed from the side (front to rear). This
amount will vary depending on the load, location of load, condition of existing suspension and personal preference.
N
OTE
:
Too much air pressure in the air helper springs will result in a firmer ride, while too little air pressure will not allow the improvement
in ride and handling that is possible. TO PREVENT POSSIBLE DAMAGE MAINTAIN A MINIMUM OF 10 psi IN
THE AIR HELPER SPRINGS AT ALL TIMES. AFTER LOADING, YOU MAY USE UP TO 100 psi PER
SIDE TO LEVEL THE TRUCK.
WHEN THE TRUCK IS LIFTED INTO THE AIR FOR SERVICE, DEFLATE BOTH AIR SPRINGS
COMPLETELY. AFTERWARDS, RE-INFLATE TO 10 psi PRIOR TO DRIVING.
